Measurement of Anteroposterior diameters of normal brainstem by Magnetic Resonance Imaging
Journal of Gandaki Medical College, 2019 Aim: The aim of this study is to assess the anteroposterior diameter of brainstem (midbrain, pons and medulla) of normal Nepalese people to establish normal ranges and to correlate the measurement with patient’s age and gender. Method: The study is a

Derivative-free superiorization with component-wise perturbations [PDF]
arXiv, 2018 Superiorization reduces, not necessarily minimizes, the value of a target function while seeking constraints-compatibility. This is done by taking a solely feasibility-seeking algorithm, analyzing its perturbations resilience, and proactively perturbing its iterates accordingly to steer them toward a feasible point with reduced value of the target ...

Transcortical photothrombotic pyramidotomy model with persistent motor deficits.
PLoS ONE, 2018 Traditional pyramidotomy models have a high mortality rate from breathing difficulties and show early recovery from the induced motor deficits. This study establishes a novel pyramidotomy technique in Sprague Dawley rats that generates persistent motor ...

Derivative-Free Superiorization: Principle and Algorithm [PDF]
arXiv, 2019 The superiorization methodology is intended to work with input data of constrained minimization problems, that is, a target function and a set of constraints. However, it is based on an antipodal way of thinking to what leads to constrained minimization methods.

Displaced retinal ganglion cells in albino and pigmented rats
Frontiers in Neuroanatomy, 2014 We have studied in parallel the population of displaced retinal ganglion cells (dRGCs) and normally placed (orthotopic RGCs, oRGCs) in albino and pigmented rats. Using retrograde tracing from the optic nerve, from both superior colliculi (SC) or from the

Strict Fejér Monotonicity by Superiorization of Feasibility-Seeking Projection Methods [PDF]
arXiv, 2014 We consider the superiorization methodology, which can be thought of as lying between feasibility-seeking and constrained minimization. It is not quite trying to solve the full fledged constrained minimization problem; rather, the task is to find a feasible point which is superior (with respect to the objective function value) to one returned by a ...

Microglial dynamics after axotomy-induced retinal ganglion cell death
Journal of Neuroinflammation, 2017 Background Microglial cells (MCs) are the sentries of the central nervous system. In health, they are known as surveying MCs because they examine the tissue to maintain the homeostasis.

Superiorization of Preconditioned Conjugate Gradient Algorithms for Tomographic Image Reconstruction [PDF]
arXiv, 2018 Properties of Superiorized Preconditioned Conjugate Gradient (SupPCG) algorithms in image reconstruction from projections are examined. Least squares (LS) is usually chosen for measuring data-inconsistency in these inverse problems. Preconditioned Conjugate Gradient algorithms are fast methods for finding an LS solution. However, for ill-posed problems,
